WASTE-VALVE-OPIERVATING M EANS.

$PECIFIGATION forming part of Letters Patent No. 654,600, dated Ju1y31,i900.

' Application filed April 18, 1899. Serial No. 713,436. (No model.)

Be it known that I, WILLIAM BUNTING, J r., a citizen of the UnitedStates, and a resident of New York, (Flushing) in the county ofQueensand State of New York, have invented certain new and usefulImprovements in- WVaste-Valve-Operating Means, of which the following isa specification.

This invention relates to an improved op erating device for thewaste-plug of a basin or bath, which is simple and cheaply made and yetvery effective for the purpose intended. V i

Numerous prior devices of this nature have been constructed in which ahorizontal reciprocating rod bears against a projection having aninclined surface; 'so that when the rod is forced inwardly the plug israised and when the rod is withdrawn the plug falls to its seat. Thesedevices have been found unsatisfactory and obj ectionable for severalreasons, among the most important of which is the liability of thefailure of the stopper to drop after it has been raised and also theneces sity in some cases of providing the sides of the spud withlongitudinal gnide grooves for the depending guide of the'stopper. Theseguide-grooves in the spud are particularly necessary when the stem ofthe waste-valve consists of a fiat guide or feather, the width of whichis approximately the same as the diameter of the spud; This formofguideis very desirable, as it' does not obstruct the waste-passage toany material extent and is strong and very cheaply made. Ithas beenfound in practice that these guide-grooves are objectionable because inuse they become badly clogged, so that the plug cannot be raised orlowered, and, moreover, as these grooves must be'cast inthe spud theymust be left rough, as they can only be smoothed up slightly with afile,it being impracticable to plane them out by a machine. In orderthat this guiding stem or feather may work in anyway satisfactorily, ithas been necessary to make the feather fit very loosely in theguide-grooves of the spud,'with the result that the stopper is veryimperfectly guided. I obviate these and other defects by my invention,which consists, broadly, in placing the reciprocating rod'at an angle tothe hori- 'zontal and providing the plug with a hori-' zontal surfaceonwhich the rod operates.

My inventionfurther consists in providing the end of the operating-rodwith a slot through which the feather or stem passes, so that the saidstem will be nicely guided without the necessity of other guiding meansbeing provided.

For a more complete understanding of my invention attention is called tothe accompanying drawings, in Which Figure 1 is an elevation partly incross-section, showing one form of my device applied to a basin. Fig. 2is a cross-section on the line m a: of Fig. 1. Fig. 3 is an elevation,partly in cross-section, showing a second form of my device. Figs. 4, 5,and 6 are detail views.

Referring to the form of my device shown in Fig. 1, the bowl lis of anywell-known form. A vertical push-rod 2, having a handle 3, passesthrough the slab 4 and the sleeve 5,the latter being secured to the slabin any-well known manner. A bracket 6 is screwed onto the lower end ofsaid sleeve and is locked in place by the nut 7. A lever Sis provided.in the end of said bracket. The spud 9 of the basin is provided with atubular projection 10, which inclines downwardly from the spud. 'A roll11 is nicely fitted in said projection 10, and a nut 12, which screwsonto the end of said projection, clamps a packingwasher between itselfand the end of said projection, so'that there is no danger of leak ageabout the rod 11. The lower ends of rods 2 and 11 are each provided witha stirrup 13 14, through which the opposite ends of lever 8 pass. Theinner end of rod 11 is split by a slot 15, as shown inFigs. 2 and 6, anda pin 16 passes through the rod near the end thereof and across the slot15.

The Waste-plug 17 is provided with an elon gated flat feather 18, whichextends down into the spud O. The thickness of this feather is slightlyless than the widthof-the slot 15 and is provided with ahofizontal slot19, which extends from one side thereof to within a short distance ofthe other side. Said slot is of slightly-greater width than the diametertherein.

-'To place the plug in its proper position with respect to rod 11, thehandle 3 is pulled up to its fullest extent, so that the rod 11 will beWithdrawn to such an extent that the pin 16 is slightly beyond the edgeof feather 18. The plug is dropped into the waste-hole at such a"position that the edge of the feather passes into the end of the slot 15of the rod 11, the pin 16 being set far enough back from the end thereofto permit a positive engagement of the split end of the rod with thefeather of the plug at all times when the plug is in position, so thatwhen it is once placed in position it cannot be turned orget out ofplace unless it is displaced by lifting it up. The operation of thisarrangement will be apparent. When it is desired to close thewasteoutlet, thehandle 3 is lifted, drawing the rod 11 outwardly anddownwardly, the pin 16, bearing on the under side of slot 19, drawingplug 17 to its seat. When it is desired to lift the plug, the handlewill be pressed down.

In the modification shown in Fig. 3 I provide an arrangement of partswhich is. for certain reasons somewhat more desirable than that abovedescribed. In this figure the rotatable shaft 20 is suitably journaledin the sleeve 20, and the slab is provided with a handle 21 at its upperend and at its lower end with an arm having an upwardly-projectingfinger 22. The spud 23 is provided with a tubular projection 24:, whichis inclined upwardly from the spud and has the rod 25 located therein.This rod 25 is almost identically the same in construction as rod 11, itbeing provided with a slotand pin at the inner end, as previouslydescribed. Secured to the outer endof rod 25 is a shaft-guide 26, havingthe elongated opening 27 therein in line with the rod 25. This openingis of sufficient width to permit the shaft 20 to pass therethrough. andof sufficient length to permit the desired lateral movement of said rod25. Said guide is also provided with a notch 28 at one side thereof,said notch having friction-rollers 29 journaled in each side. The finger22 is located in said notch, so that when the shaft 20 is rotated itbears against said rollers, drawing the rod 25outwardlyorforcingitinwardly. Obviously the motion of the guide will beboth upward and lateral, the length of arm 22 being sufficient to causethe necessary lateral movement and the length of the finger 22sufficient to permit the necessary upward movement. The plug 17 and itsfeather 18 are of the same form as that shown in Fig. 1, with theexception that the notch 19 is made near the bottom of the feather andis cut away at one side, as shown at 19". When the plug is to beinserted, the rod 20 is rotated so that the rod 25 will be forced in asfar as possible. The plug is then dropped inplace, care being taken thatthe feather passes into the slotin the end of the rod and that the outerend of slot 19 in the feather is turned away from the side which the rodenters, so that pin 16 passes through the opening 19" in the slot 19'.The feather 18 by passing through the slot in the endof the rod issecurely held against rotation, so that it cannot become misplaced, andas the slotted portion of the rod is arranged in a diagonal positionwith respect to said stem it engages said stem throughout a considerableportion of its length, so that the rod will securely hold the same in avertical position when the valve is lifted from its seat. As the stem isthus perfectly guided by the rod, it is unnec-- essary to form guidesfor the same in the side of the spud. The operation of the modificationneedslittle explanation. Then the handle 21 is turned so that the rod 25is drawn outwardly and upwardly, the plug will be lifted and will againbe lowered when the handle is turned in the opposite direction.-

The construction shown in this figure is somewhat more desirable thanthat shownin Fig. 1, for the reason that the plug is guided somewhatbetter and because it has the tubular projection 24 inclined upwardlyinstead of downwardly, whereby all danger of leakage around the rod 25is avoided. By having the operatingrod inclined upwardly from thewaste-pipe I can also arrange the operating means very compactly. Themost important advantage resulting from the arrangement of theoperating-roddiagonally of the Valvestem is that it provides a perfectguiding means therefor, so that it is unnecessary to provide the spudwith internal guides such as have before been necessary. I am thusenabled to bore out the spud after it is cast, leaving the passageperfectly smooth, so that there is no danger of threads, hair, andothermatter catching therein.

It will thus be seen that I have provided a waste-valve-operatin g meanswhich is simple and durable and unlikely to get out of order.

My invention may be applied to the valve of a bath-tub or sink, as willbe obvious.

Having described my invention, what I claim as new, and desire to secureby Letters Patent of the United States, is as follows:
